Genetic defects of the endosomal 'ESCRT' machinery in Drosophila have been found to cause loss of epithelial cell polarity, accompanied by overproliferation of mutant and adjacent wild-type cells. These results can be attributed to defective endocytosis of transmembrane proteins that control cell polarity and proliferation, including Crumbs and Notch.
已发现果蝇内体“ESCRT”机制的基因缺陷会导致上皮细胞极性丧失,并伴有突变细胞和相邻野生型细胞的过度增殖。这些结果可归因于控制细胞极性和增殖的跨膜蛋白(包括Crumb和Notch)的内吞作用缺陷。
